PROBLEM TO BE SOLVED: To provide an opposed track joint having an improved controllability. SOLUTION: A constant velocity fixing ball joint in the form of the opposed track joint comprises an outer joint member, an inner joint member, a torque transmit ball housed in a paired track having an outer track and an inner track, and a ball cage having a cage window guided to a plane on which an angle equally divided into two when the ball is held in a common plane and the joints are connected together. A first outer track forms a first paired track with a first inner track. The tracks run in a first axial direction toward the connecting end of the inner joint member, are different from each other and hold a first ball. A second outer track forms a second paired track with a second inner track. The tracks run in a second axial direction toward the connecting end of the outer joint member, different from each other and hold a second ball. The first paired track is positioned in the radial direction oppositely to the first paired track. The second paired track is positioned in the radial direction oppositely to the second paired track.
